THlLL-COUPLlNG.

SPECIFICATION forming part of Letters Patent N0. 293,379, dated February12, 1884.

' Application filedAugust22,1883. (No model.)

To aZZ whom, it may concern:

, Be it known that I, OSCAR TOWER, of Wilson, Niagara county, New York,have invented certain new and useful Improvements in Thill-Oouplings, ofwhich the following is a description.

My invention relates to an improvement in thill-couplings; and itconsists in the combination of the axle, the clip, and a recessed block,which is secured to the axle by means of the clip, and which has aconical portion to receive the coupling, and a screw-threaded portion toreceive the nut, with the coupling, the clamping-nut, and a pin to keepthe nut in place, all of which will be more fully described hereinafter.

Figure 1 is a perspective of my invention complete. Fig. 2 is a similarview of the block and pin. Fig. 3 is a perspective of the coupling. Fig.4 is a side elevation of my invention.

A represents the axle, B the couplingblock, and O the clip. The block Bhas a recess, H, formed in its top, so as to receive the lower edge ofthe axle therein, in order to prevent the block from having any endwisemotion, and to enable it to be secured more .rigidly to the axle thancould otherwise be The lower ends of the clip pass down through theblockand clamp it against-the uni done.

der side of the axle, as shown. That portion,

I, of the block which extends beyond the front of the axle is madetapering, so as to prevent any tendency on the part of the coupling F towork loose, and to enable the coupling to be more rigidly held thancould be done upon a straight portion. The coupling F, of the formshown, is passed over the screw-threaded portion J upon the taperingportion I, and is, then rigidly clamped in place, after the thill-' ironG has been passed down over its top, by the nut E upon thescrew-threaded portion J After the thill-iron is placed in position, thepiece of rubber H is placed behind it, and then the nut is screwed up inplace. The

opening 0 through the lower part of the block is also made tapering, soas to conform to the shape of the tapering portion I of the block, andso that the block can be fed forward until it is rigidly held -in place.Through the screw-threaded portion J of the block B-is made a verticalhole, D, through which the pin D is passed, for the purpose ofpreventing the nut E from working loose.

Having thus described my invention, I claim- 7 In a tliill-coupling, thecombination of the axle, clip, block B, having the tapering portion I,screw-threaded portion J, and hole D, with the coupling 13, nut E, andpin D, the parts being combined and arranged to operate substantially asshown.
